Description

Supplementary braking thrust unit for brake and method thereof
The stacked braking thrust unit of brake and the stacked braking method and technology field of brake
The present invention relates to brake, and in particular to the improvement of the pushing meanss of normally closed brake, and be particularly suitable for use in the normally engaged brakes such as tile type and tray type structure.The invention further relates to a kind of stacked braking method of brake.Background technology '
Brake is mainly made up of brake portion and pusher or pushing meanss.Publication date has been the patent document public affairs Jian that August 22 days, public No. Jian in 2007 is CN2937582, and (application number 200620050535. 0) is a kind of " variable force driving unit for being used for brake ", the pusher is connected with the actuating arm hinged in brake portion by its push rod and acts on brake portion so that brake portion realizes working condition.The structure of the pusher includes drive device and the liquid pump driven by the drive device and stores liquid case, hydraulic cylinder, the import of liquid pump is with storing communicating for liquid case, the outlet of liquid pump is communicated with the driving sap cavity of hydraulic cylinder, and the non-driven sap cavity of hydraulic cylinder is communicated with storing liquid case.When being such as applied to normally closed type braking, the push rod of pusher extend out to set position, and release the braking of normally off, after push rod is retracted return, recover the normally closed braking of brake portion, the pusher can only make brake portion produce the disposable braking for resetting normally off when realizing the operation of braking procedure.The content of the invention
It is an aspect of the invention to provide a kind of stacked braking thrust unit of brake.For normally closed brake, this stacked braking thrust unit, the braking that normally closed brake individually resets normally off can not only be met, and after normally closed on-position is resetted, as needed, stacked braking can be produced again, produce and brake again, braking frequently operating mode can be applied individually to any by beating Jian and the normally closed braking of the recovery course of work, and make the normally closed course of work braked and locate on-position with stacked braking, braking when needs are more solid and reliable can be used, such as being braked object and being in need not frequently brake or in knocking off, the braking during states such as shut-down, to increase the insensitivity for being braked object under braking quiescent conditions.
Technical scheme is illustrated referring to Fig. 1, and this stacked braking thrust unit includes pusher 1, promotes the push rod of act 1（7) brake portion is acted on（9) brake arm in（10), improved structure is that the stacked braking thrust unit of the brake also includes stacked braking mechanism, and the stacked braking mechanism acts on brake arm（.10 stacked braking) is realized.There are many change structures in the stacked braking mechanism of the present invention.
For example, referring to Fig. 1, its course of work is to pass through individually operated pusher（1) brake portion, is realized（9 ) In normally closed braking deactivate and restore normally closed braking, when needing stacked braking, brake portion can be made by individually operated stacked braking mechanism（9) two brake arms in（10) trend for being inwardly indented or producing and be inwardly indented is produced again, realizes the braking again of superposition.
The invention further relates to a kind of stacked braking method of brake, the brake includes brake arm, pusher and stacked braking mechanism, comprised the following steps：Braking action is applied to brake arm using pusher；The stacked braking of brake is realized to the further braking action of brake arm application with using stacked braking mechanism.
With background technology ratio, what the present invention had has the technical effect that：
1st, because the present invention is provided with stacked braking mechanism, and organically combined with pusher, the brake arm of brake portion is acted on by corresponding component, therefore, after the braking for causing brake to recover normally off, also stacked braking can be produced to being braked object, not only cause brake to meet the brake request of working condition, and produced stacked braking, make the braking for being braked object relatively reliable.
2, because the pusher in the present invention and stacked braking mechanism can be braked by individually operated respectively, under the operating mode frequently braked, the need for frequent damped condition being met by the operation to pusher, during if desired for more solid and reliable braking, individually operated stacked braking mechanism it can be overlapped braking again, especially need not frequently it brake or in knocking off when being braked object and be in, during suspended state, normally closed braking and stacked braking can be made while in on-position, increase is braked insensitivity of the object under braking quiescent conditions, effectively take precautions against because strong wind etc. is to being braked influence or destruction that object is likely to cause, there is good protection effect to being braked object.
3rd, because the present invention is provided with stacked braking mechanism on the basis of existing technology, to being braked the braking again that object can be also overlapped after normally closed braking is implemented, therefore, make a normally closed brake that there is the braking function and effect of two normally engaged brakes, multiple stacking braking can be carried out to being braked object when setting multi-stage superimposed arrestment mechanism, makes a normally closed brake that there is the braking function and effect of many normally engaged brakes.
4th, using the normally closed brake of the present invention, due to braking function and effect with two or many normally engaged brakes, therefore, for two or many similar brakes, can save consumptive material, reduction manufacturing cost and use cost, energy consumption is reduced, and the space needed for installation two or many brakes can be reduced.
